Introduction: Apart from many positive changes associated with technical civilization, there are also – from the health point of view – some threats. The reduction in the level of physical activity is one of them. The aim of the study was to investigate whether there are any relationships between children’s physical activity and behaviors, and to assess the impact of the adults’ activity on their children’s habits.
Material and methods: The study involved a group of 340 children aged 7–12 years (mean age: 9.81 ±1.7) and their parents. In order to evaluate children’s physical activity and the amount of time that they spend with electronic devices, an original questionnaire and the IPAQ questionnaire were used.
Results: Children usually use electronic devices between 2 and 7 days per week (mean: 4.74 ±0.86), regardless of sex (p > 0.09) and spend between 5 and 1620 min per week (mean: 459.46 ±308.1) with their mobile phone, tablet, PCs and TVs. 67.92% of boys and 69.61% of girls lead an active lifestyle. The children’s activity level depends on their parents’ level of activity (p < 0.000001). Parents of semi-active children lead a lifestyle with a moderate level of physical activity.
Conclusions: The level of physical activity in younger children depends on the children’s relationship with their parents and their level of activity. Children spend a lot of free time with their electronic devices. It is necessary to develop and implement activities intended to raise awareness of children and their families about the effects of hypokinesis.
